move asm/unaligned.h to linux/unaligned.h
asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h |

perf tools improvements and fixes for v6.12:
- Use BPF + BTF to collect and pretty print syscall and tracepoint arguments in
'perf trace', done as an GSoC activity.
- Data-type profiling improvements:
- Cache debuginfo to speed up data type resolution.
- Add the 'typecln' sort order, to show which cacheline in a target is hot or
cold. The following shows members in the cfs_rq's first cache line:
$ perf report -s type,typecln,typeoff -H
...
- 2.67% struct cfs_rq
+ 1.23% struct cfs_rq: cache-line 2
+ 0.57% struct cfs_rq: cache-line 4
+ 0.46% struct cfs_rq: cache-line 6
- 0.41% struct cfs_rq: cache-line 0
0.39% struct cfs_rq +0x14 (h_nr_running)
0.02% struct cfs_rq +0x38 (tasks_timeline.rb_leftmost)
- When a typedef resolves to a unnamed struct, use the typedef name.
- When a struct has just one basic type field (int, etc), resolve the type
sort order to the name of the struct, not the type of the field.
- Support type folding/unfolding in the data-type annotation TUI.
- Fix bitfields offsets and sizes.
- Initial support for PowerPC, using libcapstone and the usual objdump
disassembly parsing routines.
- Add support for disassembling and addr2line using the LLVM libraries,
speeding up those operations.
- Support --addr2line option in 'perf script' as with other tools.
- Intel branch counters (LBR event logging) support, only available in recent
Intel processors, for instance, the new "brcntr" field can be asked from
'perf script' to print the information collected from this feature:
$ perf script -F +brstackinsn,+brcntr
# Branch counter abbr list:
# branch-instructions:ppp = A
# branch-misses = B
# '-' No event occurs
# '+' Event occurrences may be lost due to branch counter saturated

- Support Timed PEBS (Precise Event-Based Sampling), a recent hardware feature
in Intel processors.
- Add 'perf ftrace profile' subcommand, using ftrace's function-graph tracer so
that users can see the total, average, max execution time as well as the
number of invocations easily, for instance:

for the main sample.
- Improve the BPF based sample filter, allowing root to setup filters in bpffs
that then can be used by non-root users.
- Allow filtering by cgroups with the BPF based sample filter.
- Allow a more compact way for 'perf mem report' using the -T/--type-profile and
also provide a --sort option similar to the one in 'perf report', 'perf top',

arm64: vDSO: Wire up getrandom() vDSO implementation
Hook up the generic vDSO implementation to the aarch64 vDSO data page. The _vdso_rng_data required data is placed within the _vdso_data vvar page, by using a offset larger than the vdso_data. The vDSO function requires a ChaCha20 implementation that does not write to the stack, and that can do an entire ChaCha20 permutation. The one provided uses NEON on the permute operation, with a fallback to the syscall for chips that do not support AdvSIMD. This also passes the vdso_test_chacha test along with vdso_test_getrandom. The vdso_test_getrandom bench-single result on Neoverse-N1 shows: vdso: 25000000 times in 0.783884250 seconds libc: 25000000 times in 8.780275399 seconds syscall: 25000000 times in 8.786581518 seconds A small fixup to arch/arm64/include/asm/mman.h was required to avoid pulling kernel code into the vDSO, similar to what's already done in arch/arm64/include/asm/rwonce.h.

This is due to kernel include/linux/limits.h being included instead of
libc's limits.h.
This is because directory include/ is added through option -isystem so
it goes prior to glibc's include directory.
Replace -isystem by -idirafter.
But this implies that now tools/include/linux/linkage.h is included
instead of include/linux/linkage.h, so define a stub for
SYM_FUNC_START() and SYM_FUNC_END().

perf: cs-etm: Support version 0.1 of HW_ID packets
v0.1 HW_ID packets have a new field that describes which sink each CPU writes to. Use the sink ID to link trace ID maps to each other so that mappings are shared wherever the sink is shared. Also update the error message to show that overlapping IDs aren't an error in per-thread mode, just not supported. In the future we can use the CPU ID from the AUX records, or watch for changing sink IDs on HW_ID packets to use the correct decoders.

mm/memblock: introduce a new helper memblock_estimated_nr_free_pages()
During bootup, system may need the number of free pages in the whole system to do some calculation before all pages are freed to buddy system. Usually this number is get from totalram_pages(). Since we plan to move the free pages accounting in __free_pages_core(), this value may not represent total free pages at the early stage, especially when CONFIG_DEFERRED_STRUCT_PAGE_INIT is enabled. Instead of using raw memblock api, let's introduce a new helper for user to get the estimated number of free pages from memblock point of view.

perf annotate: Add disasm_line__parse() to parse raw instruction for powerpc
Currently, the perf tool infrastructure uses the disasm_line__parse function to parse disassembled line. Example snippet from objdump: objdump --start-address=<address> --stop-address=<address> -d --no-show-raw-insn -C <vmlinux> c0000000010224b4: lwz r10,0(r9) This line "lwz r10,0(r9)" is parsed to extract instruction name, registers names and offset. In powerpc, the approach for data type profiling uses raw instruction instead of result from objdump to identify the instruction category and extract the source/target registers. Example: 38 01 81 e8 ld r4,312(r1) Here "38 01 81 e8" is the raw instruction representation. Add function "disasm_line__parse_powerpc" to handle parsing of raw instruction. Also update "struct disasm_line" to save the binary code/ With the change, function captures: line -> "38 01 81 e8 ld r4,312(r1)" raw instruction "38 01 81 e8" Raw instruction is used later to extract the reg/offset fields. Macros are added to extract opcode and register fields. "struct disasm_line" is updated to carry union of "bytes" and "raw_insn" of 32 bit to carry raw code (raw). Function "disasm_line__parse_powerpc fills the raw instruction hex value and can use macros to get opcode. There is no changes in existing code paths, which parses the disassembled code. The size of raw instruction depends on architecture. In case of powerpc, the parsing the disasm line needs to handle cases for reading binary code directly from DSO as well as parsing the objdump result. Hence adding the logic into separate function instead of updating "disasm_line__parse". The architecture using the instruction name and present approach is not altered. Since this approach targets powerpc, the macro implementation is added for powerpc as of now. Since the disasm_line__parse is used in other cases (perf annotate) and not only data tye profiling, the powerpc callback includes changes to work with binary code as well as mnemonic representation. Also in case if the DSO read fails and libcapstone is not supported, the approach fallback to use objdump as option. Hence as option, patch has changes to ensure objdump option also works well.

Pull slab updates from Vlastimil Babka:
"The most prominent change this time is the kmem_buckets based
hardening of kmalloc() allocations from Kees Cook.
We have also extended the kmalloc() alignment guarantees for
non-power-of-two sizes in a way that benefits rust.
The rest are various cleanups and non-critical fixups.
- Dedicated bucket allocator (Kees Cook)
This series [1] enhances the probabilistic defense against heap
spraying/grooming of CONFIG_RANDOM_KMALLOC_CACHES from last year.
kmalloc() users that are known to be useful for exploits can get
completely separate set of kmalloc caches that can't be shared with
other users. The first converted users are alloc_msg() and
memdup_user().
The hardening is enabled by CONFIG_SLAB_BUCKETS.
- Extended kmalloc() alignment guarantees (Vlastimil Babka)
For years now we have guaranteed natural alignment for power-of-two
allocations, but nothing was defined for other sizes (in practice,
we have two such buckets, kmalloc-96 and kmalloc-192).
To avoid unnecessary padding in the rust layer due to its alignment
rules, extend the guarantee so that the alignment is at least the
largest power-of-two divisor of the requested size.
This fits what rust needs, is a superset of the existing
power-of-two guarantee, and does not in practice change the layout
(and thus does not add overhead due to padding) of the kmalloc-96
and kmalloc-192 caches, unless slab debugging is enabled for them.
- Cleanups and non-critical fixups (Chengming Zhou, Suren
Baghdasaryan, Matthew Willcox, Alex Shi, and Vlastimil Babka)
Various tweaks related to the new alloc profiling code, folio
conversion, debugging and more leftovers after SLAB"

perf tools fixes and improvements for v6.10:
- Add Kan Liang to MAINTAINERS as a perf tools reviewer.
- Add support for using the 'capstone' disassembler library in various tools,
such as 'perf script' and 'perf annotate'. This is an alternative for the
use of the 'xed' and 'objdump' disassemblers.
- Data-type profiling improvements:
Resolve types for a->b->c by backtracking the assignments until it finds
DWARF info for one of those members
Support for global variables, keeping a cache to speed up lookups.
Handle the 'call' instruction, dealing with effects on registers and handling
its return when tracking register data types.
Handle x86's segment based addressing like %gs:0x28, to support things like
per CPU variables, the stack canary, etc.
Data-type profiling got big speedups when using capstone for disassembling.
The objdump outoput parsing method is left as a fallback when capstone fails or
isn't available. There are patches posted for 6.11 that to use a LLVM
disassembler.
Support event group display in the TUI when annotating types with --data-type,
for instance to show memory load and store events for the data type fields.
Optimize the 'perf annotate' data structures, reducing memory usage.
Add a initial 'perf test' for 'perf annotate', checking that a target symbol
appears on the output, specifying objdump via the command line, etc.
- Integrate the shellcheck utility with the build of perf to allow catching
shell problems early in areas such as 'perf test', 'perf trace' scrape
scripts, etc.
- Add 'uretprobe' variant in the 'perf bench uprobe' tool.
- Add script to run instances of 'perf script' in parallel.
- Allow parsing tracepoint names that start with digits, such as
9p/9p_client_req, etc. Make sure 'perf test' tests it even on systems
where those tracepoints aren't available.
Vendor Events:
- Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand Ridge, Ice
Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra Forest, Sky Lake X,
Sky Lake and Snow Ridge X. Remove info metrics erroneously in TopdownL1.
- Add AMD's Zen 5 core and uncore events and metrics. Those come from the
"Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh Processors"
document, with events that capture information on op dispatch, execution and
retirement, branch prediction, L1 and L2 cache activity, TLB activity, etc.
- Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/AmpereOneX.
Miscellaneous:
- Sync header copies with the kernel sources.
- Move some header copies used only for generating translation string tables
for ioctl cmds and other syscall integer arguments to a new directory under
tools/perf/beauty/, to separate from copies in tools/include/ that are used
to build the tools.
- Introduce scrape script for several syscall 'flags'/'mask' arguments.
- Improve cpumap utilization, fixing up pairing of refcounts, using the right
iterators (perf_cpu_map__for_each_cpu), etc.
- Give more details about raw event encodings in 'perf list', show tracepoint
encoding in the detailed output.
- Refactor the DSOs handling code, reducing memory usage.
- Document the BPF event modifier and add a 'perf test' for it.
- Improve the event parser, better error messages and add further 'perf test's
for it.
- Add reference count checking to 'struct comm_str' and 'struct mem_info'.
- Make ARM64's 'perf test' entries for the Neoverse N1 more robust.
- Tweak the ARM64's Coresight 'perf test's.
- Improve ARM64's CoreSight ETM version detection and error reporting.
- Fix handling of symbols when using kcore.
- Fix PAI (Processor Activity Instrumentation) counter names for s390 virtual
machines in 'perf report'.
- Fix -g/--call-graph option failure in 'perf sched timehist'.
- Add LIBTRACEEVENT_DIR build option to allow building with libtraceevent
installed in non-standard directories, such as when doing cross builds.
- Various 'perf test' and 'perf bench' fixes.
- Improve 'perf probe' error message for long C++ probe names.

- Allow parsing tracepoint names that start with digits, such as
9p/9p_client_req, etc. Make sure 'perf test' tests it even on
systems where those tracepoints aren't available
- Add Kan Liang to MAINTAINERS as a perf tools reviewer
- Add support for using the 'capstone' disassembler library in
various tools, such as 'perf script' and 'perf annotate'. This is
an alternative for the use of the 'xed' and 'objdump' disassemblers
Data-type profiling improvements:
- Resolve types for a->b->c by backtracking the assignments until it
finds DWARF info for one of those members
- Support for global variables, keeping a cache to speed up lookups
- Handle the 'call' instruction, dealing with effects on registers
and handling its return when tracking register data types
- Handle x86's segment based addressing like %gs:0x28, to support
things like per CPU variables, the stack canary, etc
- Data-type profiling got big speedups when using capstone for
disassembling. The objdump outoput parsing method is left as a
fallback when capstone fails or isn't available. There are patches
posted for 6.11 that to use a LLVM disassembler
- Support event group display in the TUI when annotating types with
--data-type, for instance to show memory load and store events for
the data type fields
- Optimize the 'perf annotate' data structures, reducing memory usage
- Add a initial 'perf test' for 'perf annotate', checking that a
target symbol appears on the output, specifying objdump via the
command line, etc
Vendor Events:
- Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand
Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra
Forest, Sky Lake X, Sky Lake and Snow Ridge X. Remove info metrics
erroneously in TopdownL1
- Add AMD's Zen 5 core and uncore events and metrics. Those come from
the "Performance Monitor Counters for AMD Family 1Ah Model 00h- 0Fh
Processors" document, with events that capture information on op
dispatch, execution and retirement, branch prediction, L1 and L2
cache activity, TLB activity, etc
- Mark L1D_CACHE_INVAL impacted by errata for ARM64's AmpereOne/
AmpereOneX
Miscellaneous:
- Sync header copies with the kernel sources
- Move some header copies used only for generating translation string
tables for ioctl cmds and other syscall integer arguments to a new
directory under tools/perf/beauty/, to separate from copies in
tools/include/ that are used to build the tools
- Introduce scrape script for several syscall 'flags'/'mask'
arguments
- Improve cpumap utilization, fixing up pairing of refcounts, using
the right iterators (perf_cpu_map__for_each_cpu), etc
- Give more details about raw event encodings in 'perf list', show
tracepoint encoding in the detailed output
- Refactor the DSOs handling code, reducing memory usage
- Document the BPF event modifier and add a 'perf test' for it
- Improve the event parser, better error messages and add further
'perf test's for it
- Add reference count checking to 'struct comm_str' and 'struct
mem_info'
- Make ARM64's 'perf test' entries for the Neoverse N1 more robust
- Tweak the ARM64's Coresight 'perf test's
- Improve ARM64's CoreSight ETM version detection and error reporting
- Fix handling of symbols when using kcore
- Fix PAI (Processor Activity Instrumentation) counter names for s390
virtual machines in 'perf report'
- Fix -g/--call-graph option failure in 'perf sched timehist'
- Add LIBTRACEEVENT_DIR build option to allow building with
libtraceevent installed in non-standard directories, such as when
doing cross builds
- Various 'perf test' and 'perf bench' fixes
- Improve 'perf probe' error message for long C++ probe names"

contents that may be used by either the old fbdev drivers or the
newer drm display code.
- Thorsten Blum contributes cleanups for the generic bitops code
and asm-generic/bug.h
- I remove the orphaned include/asm-generic/page.h header that used to
included by long-removed mmu-less architectures.

bitops: Change function return types from long to int
Change the return types of bitops functions (ffs, fls, and fns) from long to int. The expected return values are in the range [0, 64], for which int is sufficient. Additionally, int aligns well with the return types of the corresponding __builtin_* functions, potentially reducing overall type conversions. Many of the existing bitops functions already return an int and don't need to be changed. The bitops functions in arch/ should be considered separately. Adjust some return variables to match the function return types. With GCC 13 and defconfig, these changes reduced the size of a test kernel image by 5,432 bytes on arm64 and by 248 bytes on riscv; there were no changes in size on x86_64, powerpc, or m68k.

bitmap: introduce generic optimized bitmap_size()
The number of times yet another open coded `BITS_TO_LONGS(nbits) * sizeof(long)` can be spotted is huge. Some generic helper is long overdue. Add one, bitmap_size(), but with one detail. BITS_TO_LONGS() uses DIV_ROUND_UP(). The latter works well when both divident and divisor are compile-time constants or when the divisor is not a pow-of-2. When it is however, the compilers sometimes tend to generate suboptimal code (GCC 13): 48 83 c0 3f add $0x3f,%rax 48 c1 e8 06 shr $0x6,%rax 48 8d 14 c5 00 00 00 00 lea 0x0(,%rax,8),%rdx %BITS_PER_LONG is always a pow-2 (either 32 or 64), but GCC still does full division of `nbits + 63` by it and then multiplication by 8. Instead of BITS_TO_LONGS(), use ALIGN() and then divide by 8. GCC: 8d 50 3f lea 0x3f(%rax),%edx c1 ea 03 shr $0x3,%edx 81 e2 f8 ff ff 1f and $0x1ffffff8,%edx Now it shifts `nbits + 63` by 3 positions (IOW performs fast division by 8) and then masks bits[2:0]. bloat-o-meter: add/remove: 0/0 grow/shrink: 20/133 up/down: 156/-773 (-617) Clang does it better and generates the same code before/after starting from -O1, except that with the ALIGN() approach it uses %edx and thus still saves some bytes: add/remove: 0/0 grow/shrink: 9/133 up/down: 18/-538 (-520) Note that we can't expand DIV_ROUND_UP() by adding a check and using this approach there, as it's used in array declarations where expressions are not allowed. Add this helper to tools/ as well.

tools: move alignment-related macros to new <linux/align.h>

bitops: make BYTES_TO_BITS() treewide-available
Avoid open-coding that simple expression each time by moving BYTES_TO_BITS() from the probes code to <linux/bitops.h> to export it to the rest of the kernel. Simplify the macro while at it. `BITS_PER_LONG / sizeof(long)` always equals to %BITS_PER_BYTE, regardless of the target architecture. Do the same for the tools ecosystem as well (incl. its version of bitops.h). The previous implementation had its implicit type of long, while the new one is int, so adjust the format literal accordingly in the perf code.

The main changes are: 1) Add the ability to specify and retrieve BPF cookie also for raw tracepoint programs in order to ease migration from classic to raw tracepoints, from Andrii Nakryiko. 2) Allow the use of bpf_get_{ns_,}current_pid_tgid() helper for all program types and add additional BPF selftests, from Yonghong Song. 3) Several improvements to bpftool and its build, for example, enabling libbpf logs when loading pid_iter in debug mode, from Quentin Monnet. 4) Check the return code of all BPF-related set_memory_*() functions during load and bail out in case they fail, from Christophe Leroy. 5) Avoid a goto in regs_refine_cond_op() such that the verifier can be better integrated into Agni tool which doesn't support backedges yet, from Harishankar Vishwanathan. 6) Add a small BPF trie perf improvement by always inlining longest_prefix_match, from Jesper Dangaard Brouer. 7) Small BPF selftest refactor in bpf_tcp_ca.c to utilize start_server() helper instead of open-coding it, from Geliang Tang. 8) Improve test_tc_tunnel.sh BPF selftest to prevent client connect before the server bind, from Alessandro Carminati. 9) Fix BPF selftest benchmark for older glibc and use syscall(SYS_gettid) instead of gettid(), from Alan Maguire. 10) Implement a backward-compatible method for struct_ops types with additional fields which are not present in older kernels, from Kui-Feng Lee. 11) Add a small helper to check if an instruction is addr_space_cast from as(0) to as(1) and utilize it in x86-64 JIT, from Puranjay Mohan. 12) Small cleanup to remove unnecessary error check in bpf_struct_ops_map_update_elem, from Martin KaFai Lau. 13) Improvements to libbpf fd validity checks for BPF map/programs, from Mykyta Yatsenko. * tag 'for-netdev' of https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next: (38 commits) selftests/bpf: Fix flaky test btf_map_in_map/lookup_update bpf: implement insn_is_cast_user() helper for JITs bpf: Avoid get_kernel_nofault() to fetch kprobe entry IP selftests/bpf: Use start_server in bpf_tcp_ca bpf: Sync uapi bpf.h to tools directory libbpf: Add new sec_def "sk_skb/verdict" selftests/bpf: Mark uprobe trigger functions with nocf_check attribute selftests/bpf: Use syscall(SYS_gettid) instead of gettid() wrapper in bench bpf-next: Avoid goto in regs_refine_cond_op() bpftool: Clean up HOST_CFLAGS, HOST_LDFLAGS for bootstrap bpftool selftests/bpf: scale benchmark counting by using per-CPU counters bpftool: Remove unnecessary source files from bootstrap version bpftool: Enable libbpf logs when loading pid_iter in debug mode selftests/bpf: add raw_tp/tp_btf BPF cookie subtests libbpf: add support for BPF cookie for raw_tp/tp_btf programs bpf: support BPF cookie in raw tracepoint (raw_tp, tp_btf) programs bpf: pass whole link instead of prog when triggering raw tracepoint bpf: flatten bpf_probe_register call chain selftests/bpf: Prevent client connect before server bind in test_tc_tunnel.sh selftests/bpf: Add a sk_msg prog bpf_get_ns_current_pid_tgid() test ... ==================== Link: https://lore.kernel.org/r/20240325233940.7154-1-daniel@iogearbox.net Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
